the EVM has a path for using the DRV8301 2-ch PGA or 3 external amps. This is because in some cases you want to use all three currents and we weren't sure if this would work very well just using 1 external. When we designed the BOOSTXL-DRV8301 we actually…
Hi SHH,
Please note that the DS100KR401 is a redriver/repeater, not a retimer because it does not contain a CDR block within the device.
1. Yes, it will likely be possible you need to configure the DS100KR401 before use. This is because the default…
Hi Jeffery,
Pg 11, Fig. 9 is an open-loop gain/phase (Aol) plot for the operational amplifier (OPA) that supplies either the output in either voltage output, or current output modes. Actually, the Aol curves are very normal and exhibit well behaved…
Hi Gideon,
I have built an OPA847 circuit on one of our unpopulated demonstration boards ( DEM-OPA-SO-1B ) and have not seen this issue.
Are you seeing this behavior on your own PC board or on a DEM board? If you are seeing this behavior on your…
both EVM baseboards are identical and you must purchase with a controlCARD
the EVM baseboard has two different current sensing circuits
1. using the 2 PGAs of DRV8301: this is scaled to ~ +/- 60A which we use with DRV8301-HC-C2-KIT software examples…

"The figure below is a plot performed with the same load shown the last time (it was a rapid test, I will perform a variable load tomorrow =)). The weird phase currents appears when Vs≈0.9 and motorSpeed≈800RPM which is under the rated speed (868.6RPM…
Ivan,
The issue happens when the device is plug out and plug in again after configuring Microphone Mute.
Please refer to the below procedure using DEM-PCM2912A and my laptop.
O/S: Windows 7, Service Pack 1
Step #1: Enable “Microphone Mute…
Other Parts Discussed in Thread: PCM3168A , PUREPATH-CMBEVM Hello,
for a multichannel audio application I'm looking for a evaluation board for the PCM3168A.
The product page has no link to an EVM, it links to an overview page (Quick Search Selection…
